Can You Turn on the Air Conditioning When the Car Is Off in Summer?
2 Answers
In summer, you can turn on the air conditioning when the car is off, but it won't provide cooling functionality. Additionally, prolonged use can easily lead to battery drain. Therefore, it is not recommended to keep the air conditioning on for extended periods when the engine is off. If you need ventilation, switch to the external circulation mode to allow fresh air to enter the cabin. The role of car air conditioning: Car air conditioning refers to the air conditioning system installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. The structure of car air conditioning: It generally includes a cooling system, heating system, and ventilation system. This integrated setup makes efficient use of the limited space inside the car, featuring a simple structure and ease of operation. It is the internationally popular modern car air conditioning system.
I'm a commuter who drives frequently. In the summer, when parked by the roadside waiting for someone, I definitely turn on the air conditioning, but the engine must be running—it can't rely on the battery alone to power the AC. This is because the air conditioning compressor requires the engine's power to operate. A friend of mine once rested in the garage with the AC on, and exhaust fumes leaked in, nearly causing poisoning. When I park in the sun and use the AC, I usually turn off the engine after just ten minutes to prevent draining the battery or overheating the engine. Fuel consumption increases, especially when idling with the AC on in the city—it might use up half a liter of fuel per hour. I recommend checking the car's condition first, ensuring the battery is healthy, and preferably sitting in the car with ventilation rather than sleeping for too long. Regular maintenance can prevent malfunctions, especially after frequent AC use in hot weather.
